Whm Transfer Tool Terminated Incorrectly

While moving 5 accounts from another cpanel/whm server, 4 got transferred properly and 5th one (50GB) was taking huge time. So terminated the same using abort tool. Even then it was simply showing Aborting message for 2 hours. So to stop the transfer I followed instructions in one of the thread on this forum:

Found the process ID (MASTER) for the transfer session and killed it:
kill -9 20802
